Self-Assembly of Vertically Aligned Gold Nanorod Arrays on Patterned Substrates


  • We acknowledge financial support from the Australian Research Council through an Australian Research Fellowship (U.B.). Further financial support has been received from Commonwealth Scientific and Industrial Research Organization through an OCE Science Leader position (U.B.). This work was performed in part at the Melbourne Centre for Nanofabrication, an initiative partly funded by the Commonwealth of Australia and the Victorian government.

Nanorods standing at attention! A self-assembly technique based on convective and capillary forces was used for the direct fabrication of standing arrays of gold nanorods on lithographically predefined areas (see picture). The hexagonal close-packed structure of gold nanorods creates an ideal substrate for surface-enhanced Raman spectroscopy.
